Bitmain Antminer KS3 (9.4Th)

The Bitmain Antminer KS3 (9.4Th) is a purpose-built ASIC for the KHeavyHash algorithm-primarily deployed to mine Kaspa-offering a measured hashrate of 9.4 terahashes per second with a nominal power draw of 3,500 watts and an energy efficiency of 0.372 joules per gigahash; engineered for operational resilience, it integrates advanced fault detection and an intelligent power-management module to minimize downtime and stabilize performance across variable loads, while reinforced hardware and a robust cooling architecture featuring two high-speed fans support prolonged mining sessions and help sustain high output without compromising reliability or energy efficiency. Its compact footprint (195 × 290 × 430 mm) and stable Ethernet connectivity make it suitable for both dense deployments and smaller operations, and the streamlined interface enables straightforward tuning of performance parameters for large-scale farms or independent miners. From an operational standpoint, effective deployment benefits from attention to ventilation, adequate electrical capacity with margin, routine cleaning and maintenance of fans and heatsinks, timely firmware updates and network redundancy, and placement planning to manage heat and acoustic output; when incorporated into a monitored infrastructure with these considerations, the KS3 delivers a balance of throughput, durability and energy-conscious operation that aligns with systematic, long-run mining objectives.

The Bitmain Antminer KS3 is a purpose-built KHeavyHash ASIC optimized for mining Kaspa, delivering a measured hashrate of 9.4 terahashes per second while drawing approximately 3,500 watts and achieving an energy efficiency of 0.372 joules per gigahash; its design objective balances sustained throughput and component longevity through a combination of refined silicon architecture and system-level thermal and power management. Thermal control is implemented via a compact fin-stack heat-sink arrangement paired with two high-speed fans and dynamic fan-speed control to suppress hotspots under continuous load, while the chassis’ isolated grounding and EMI-conscious layout reduce interference that can accelerate component degradation. The internal power supply and intelligent power-management firmware tolerate and compensate for voltage fluctuations, supporting an auto-recovery sequence that mitigates transient outages and reduces crash-induced downtime; firmware also exposes calibrated tuning parameters so operators can marginally trade off efficiency and stability in response to ambient temperature and network conditions. Operationally relevant form factors include a 195 × 290 × 430 mm footprint and stable Ethernet connectivity for integration into dense racks or smaller installations, and real-world deployment benefits from attention to electrical provisioning with headroom, phase-balanced loading, targeted ventilation and acoustic planning, routine cleaning of fans and heatsinks, humidity and dust control, and timely firmware and network redundancy measures to preserve long-run output. From an empirical perspective, the KS3’s combination of measured hashrate, explicit efficiency metric, fault-detection features and hardware reinforcement makes it suitable for operators who prioritize predictable long-run throughput and serviceability, provided they instrument monitoring for power quality, temperature, and hash-rate drift and plan maintenance cycles accordingly.

KHeavyHash is a cryptographic hash function that serves as the backbone of Kaspa proof-of-work consensus mechanism. This algorithm processes input data of any length and produces a fixed hash value, ensuring security and integrity in the mining process.
